User authentication for web servers

This hapi plugin adds a secure login and logout system to your app by integrating Auth0.



  • User auth is a necessity for most apps and websites.
  • User auth is difficult to do correctly on your own.
  • Secure systems should be easy to set up and use.
  • Comes with built-in login and logout routes.


npm install hapi-doorkeeper


Register the plugin on your server to add the /login and /logout routes, as well as the session strategy so that you can protect your app's routes with authentication.

const hapi = require('@hapi/hapi');
const bell = require('@hapi/bell');
const cookie = require('@hapi/cookie');
const doorkeeper = require('hapi-doorkeeper');

const server = hapi.server();

const init = async () => {
    await server.register([bell, cookie, {
        plugin  : doorkeeper,
        options : {
            sessionSecretKey : process.env.SESSION_SECRET_KEY,
            auth0Domain      : process.env.AUTH0_DOMAIN,
            auth0PublicKey   : process.env.AUTH0_PUBLIC_KEY,
            auth0SecretKey   : process.env.AUTH0_SECRET_KEY
        method : 'GET',
        path   : '/dashboard',
        config : {
            auth : {
                strategy : 'session',
                mode     : 'required'
        handler(request) {
            const { user } = request.auth.credentials;
            return `Hi ${user.name}, you are logged in! Here is the profile from Auth0: <pre>${JSON.stringify(user.raw, null, 4)}</pre> <a href="/logout">Click here to log out</a>`;
    await server.start();
    console.log('Server ready:', server.info.uri);


In the example above, only logged in users are able to access /dashboard, as denoted by the session strategy being required. If you are logged in, it will display your profile, otherwise it will redirect you to a login screen and after you log in it will redirect you back to /dashboard.

Authentication is managed by Auth0. A few steps are required to finish the integration.

  1. Sign up for Auth0
  2. Set up an Auth0 Application
  3. Provide credentials from Auth0

After users log in, a session cookie is created for them so that the server remembers them on future requests. The cookie is stateless, encrypted, and secured using flags such as HttpOnly. The user's Auth0 profile is automatically retrieved and stored in the session when they log in. You can access the profile data at request.auth.credentials.user. See hapi-auth-cookie and iron for details about the cookie implementation and security.

Note that your server must support HTTPS for everything to work properly. If you need help with that, see this How To Guide.

APIs can also be protected by the session strategy. Clients can send an Accept header with a value of application/json to indicate that they would prefer a JSON error instead of a redirect to the login page for users who are not logged in. The client can use this to show an error message or redirect the user manually, as appropriate.



Standard user authentication routes are added to your server when the plugin is registered.

GET /login

Tags: user, auth, session, login

Begins a user session. If a session is already active, the user will be given the opportunity to log in with a different account.

If users deny access to a social account, they will be redirected back to the login page so that they may try again, because they probably clicked the wrong account or provider by accident. Other login errors will be returned to the client with a 401 Unauthorized status. You may use hapi-error-page or onPreResponse to display beautiful HTML pages for them.

After logging in, users are redirected to the URL specified in the next query parameter, which defaults to /, the root of the server.

As an example, the login button on your FAQ page might look be written as <a href="/login?next=/faq">Log in</a>.

Only relative URLs are allowed in next for security reasons.

Routes that use the session strategy to require login have the next parameter set automatically for them, so that users are always sent back to the correct place.

GET /logout

Tags: user, auth, session, logout

Ends a user session. Safe to visit regardless of whether a session is active or the validity of the user's credentials. After logging out, users will be redirected to the URL specified in the next query parameter, which defaults to / (see /login for details).

Plugin options


Type: string

A passphrase used to secure session cookies. Should be at least 32 characters long and occasionally rotated. See Iron for details.


Type: string

The domain used to log in to Auth0. This should be the domain of your tenant (e.g. my-company.auth0.com) or your own custom domain (e.g. auth.my-company.com).


Type: string

The ID of your Auth0 Application, sometimes referred to as the Client ID.


Type: string

The secret key of your Auth0 Application, sometimes referred to as the Client Secret.


Type: function Default: Forward some query params from /login to Auth0

An optional event handler that receives an incoming request to the /login route and should return an object of query parameters to send to Auth0. See the providerParams option in bell for details.

By default, we forward screen as screen_hint and user as login_hint. Because Auth0's hosted login page has special behavior based on those parameters, if you visit /login?user=jane@example.com, then on the log in screen jane@example.com will be prefilled as the email address to log in with. Similarly, /login?screen=signup will cause the sign up page to display instead of log in. This makes it easy to implement "Log In" and "Sign Up" buttons on your website that go directly to the correct screen.

For details on these parameters, see Auth0's documentation on the New Universal Login Experience.

validateFunc(request, session)

Type: function

An optional event handler where you can put business logic to check and modify the session on each request. See the validateFunc option in hapi-auth-cookie for details.

This is a good place to set authorization scopes for users, if you need to restrict access to some routes for certain users.
